Life at four degrees – Features – ABC Environment Australian Broadcasting Corporation

With global climate change talks moving too slowly, scientists are now talking of a rise in global temperatures of four degrees. What would this mean for Australia?”AVERAGES ARE VERY MISLEADING,” says Professor Lesley Hughes. “An average never killed anything.”Professor Hughes, one of Australia’s Climate Commissioners, is talking about recent reports suggesting the world is heading for an average 4°C of global warming by the end of this century.Both the World Bank and the Global Carbon Project, an international group of scientists including members of CSIRO, have come to this conclusion based on the assumption that the world will do little to cut back on emissions of greenhouse gases mainly from burning fossil fuels and cutting down forests.
